The condition of microbiogical
indexes of oral cavity microflora in orthopedic patients, having bridges based
on implants
Oral microflora
represented by different types of microorganisms , it's relation determine the
microbiocenosis of oral cavity.
Oral microflora as a
highly sensitive system , reacts qualitative and quantitative shifts to
external impact of changes the state of several organs and body systems ,
general and local immunoreactivity.
Some patients after
orthopedic treatment as result the
impact of prosthetic materials can
mature the complex pathological
reactions of mucosa of the mouth and the body as a whole. It is called "
intolerance of dental structural
materials " .
The norm of oral
cavity microbiocenosis an
optimal combination between the microflora present in it , when there is no
antagonism between the individual and the species is not observed excessive
growth of some of the representatives of pathogenic or opportunistic pathogens
, is coexistence (symbiosis ) of microorganisms is irreducible to the
development of pathology.
During the violate the
symbiosis with the prevalence of goiter develops patogenic or shareware
patogenic microflora manifestation of which is manifested in the form of dental
disease
Relevance
Essential significance in
the development of dysbiosis may be insertion into the oral cavity dental
materials (in this case of dental bridges are made of acrylates )
, on which microorganisms can be
adsorbed with next active reproduction.
This can lead to dental disease and exacerbation of disease such as gingivitis
and periodontitis , etc.
The purpose of this study
is to investigate the effect of bridges made of acrylates on the
oral cavity microflora condition in
patients requiring this type of treatment.
Methods of investigation
Were examined 26 people of
both sexes , requiring orthopedic treatment by
bridges .Scraping of oral mucosa
performed by standard swab transport system company "Sarsteds" (
Germany), which allows to increase terms of transportation to bacteriological
labs to 72 hours.
Microbiological studies
included determination of total microbial count ( TBC ) by counting the
microorganism colonies , and also the definition of relations aerobic and
anaerobic flora .
For cultivation used :
-
for aerobic
and facultative bacteria -blood agar ,
Chistovich's medium, Endo agar
-
for anaerobic
bacteria Kito Torotstsis medium.
The cultivation carried
out in an incubator at 37 ° C t for 3-5
days Results of quantitative research microflora - the level of contamination
was expressed as colony-forming units per 1 ml.
Results of investigation
In the control group (
practically healthy people ) total bacterial count accounting for 1,2 ± 0,07 Uel . u , and the level of aerobes 9
and anaerobes
By 1 month after the
installation of bridges implant considered total bacterial count by 4% ( P>
0.05 ) and was 1,25 ± 0,09 Uel . u , and the number of aerobic 8.5 ( P >
0.05) , anaerobic 1.5 ( P > 0.05) .
By 3 months after orthopedic
treatment microbiological parameters did not differ from that of 1 month after
prosthesis . 1,25 ± 0,07 Uel .
In long-term of
investigation 6-12 months total
bacterial count and the ratio of aerobic / anaerobic bacteria did not differ
from benchmarks. 1,2 ± 0,08 Uel . U
Conclusions
A detailed analysis of microbiological
studies, allowed to mAKE A conclusion that installing bridges (made of
acrylates) with reliance on implants:
- do not have any significant
changes in indicators of oral microflora
- increase in total microbial count was observed at 1 month after
orthopedic treatment was 4% higher than the benchmarks.
